At room temperature, oxygen reacts with the surface of the metal. This forms a white oxide, which covers the surface. The metal below the surface does not react.

Since this atom has a total of eight electrons, it also has eight protons. The atom with eight protons in its nucleus (atomic number 8) is oxygen. Each energy level holds a certain number of electrons ...

That’s why this periodic table clock really caught our eye. [gocivici]’s idea is a simple one: light up three different elements with three different colors for hours, minutes, and seconds ...

For the last fifty or so years, the periodic table has been incomplete. Elements after uranium on the periodic table have been synthesized for the past few decades, but there were always a few ...
